Parkinsoni Rainbowfish – Melanotaenia parkinsoni
The Parkinsoni Rainbowfish (Melanotaenia parkinsoni) is a colorful, active freshwater rainbowfish known for its silvery blue-gray front half and vivid yellow to orange coloration along the rear body and fins. Mature males develop especially bright color, making this species a standout choice for planted aquariums and peaceful community tanks.
Native to coastal stream habitats of Papua New Guinea, Parkinsoni Rainbowfish are peaceful, social, and best kept in groups. When kept in a proper school, males display stronger color and more natural behavior as they interact with each other and with females.
